[v14.x backport] util: fix module inspection & instanceof check during inspect #37100

Pezmc · 2021-01-27T11:56:57Z

Backports #36178 from @BridgeAR, tagged as semver‑patch, to 14.x as per comment from @ExE-Boss

14.x is currently impacted by the bug fixed in #36178, which was originally released to 15.x in https://github.com/nodejs/node/releases/tag/v15.5.0

I followed the guide from https://github.com/nodejs/node/blob/master/doc/guides/backporting-to-release-lines.md

I don't have the Jekins permissions to schedule a node-test-pull-request CI job for this PR (37100)

Pezmc is missing the Job/Build permission

Would appreciate a review from someone more familiar with this area (cc @nodejs/modules?)

LGTM; i'll make similar changes in object-inspect.

lib/internal/util/inspect.js

+function isInstanceof(object, proto) {
+  try {
+    return object instanceof proto;
+  } catch {
+    return false;
+  }
+}
+


why is the try/catch needed? are we worried about someone defining a Symbol.hasInstance method that can throw?

Based on cb9eec9#r527685177, instanceof can throw

ah, didn't realize this was a backport PR. turns out instanceof can indeed throw when the RHS is not a function, or when it's a non-constructible function (like an arrow function or a concise method)

@BethGriggs I tried rebasing onto the latest nodejs:v14.x-staging to clean this PR after your force push and ended up with 89402af in my diff. Do you know where that came from?

Ah yes, that commit was backed out of staging as there was an npm version mismatch (ref: #37107 (comment)). We need to reland the npm update in a new PR.

For this PR, I think you could either rebase against upstream/v14.x-staging and then drop the npm commit. Or I can just cherry-pick your commits from this PR.

The good news is that the delay in fixing the npm update means we can probably squeeze this into v14.15.5 (#37074)

Re-rebased and manually dropped that commit, this PR should be good to go @BethGriggs!

@BethGriggs Anything I can do to help get this into v14.15.5?

BethGriggs · 2021-02-03T15:48:11Z

@Pezmc, I'll aim to integrate this into the v14.15.5 proposal - i'm still waiting on some other patches so haven't started updating the proposal yet. Nothing more to do on your side 🙂

Would appreciate a review on this before landing (maybe @nodejs/modules)?
